actuated butterfly valve

▶▷A sealing ring, ensuringtightness in the seat, forms a sandwich of stainlesssteel sheets layered witha soft filler of graphite. This composition is able to withstand high temperatures and ensures excellent resilience of the sealing element even during significant fluctuations of medium temperature and pressure. ▶▷The packing system consists of a series of soft graphite sealing rings preventing leakage around the shaft. Graphite is a material which perfectly seals and resists high temperatures. Optimization of the ratio between tightness around the shaft and the actuating torque can be easily achieved by tightening or loosening the nuts holding the packing flange. ▶▷Spirally wound stainless steel band with a soft graphite filler guarantees a perfect seal even with large temperature and pressure fluctuations inside the pipe.

1. Air Actuated Butterfly Valve use pneumatic actuator the advantage is Compact structure, small size, higher precision 2. Eccentric Air Actuated Butterfly Valve ues double eccentric structure has longer life and better stability 3. This butterfly valve made of high-quality WCB material casting to be stronger and more durable

▶▷ The metal hard seal butterfly valve has a two-way sealing function. It is not restricted by the flow direction of the medium during installation and is not affected by the spatial position. It can be installed in any direction. ▶▷Small opening torque, flexible and convenient, labor-saving and energy-saving. ▶▷High pressure resistance, corrosion resistance, wear resistance, long service life. ▶▷The driving device can be installed in multiple positions (rotated by 90° or 180°), which is convenient for users to use.
